So 4 months of doing nothing but stay at 80% development is something, i guess you right...
Apart from the fact that dev's percentages are one of the least reliable estimates out there - not because dev's are cheating and nobody can control it (may be true in some cases though), but because many things are unpredictable, both in software development and in creativity - the basis of your statement (continuously 80% for four months) is just false. But in these times where people like their alternative facts I guess that's par for the course.
But the main point is: I may even agree that it is prudent to wait for the first update to gauge what happens here, because we don't know. But you don't know either. You just throw vague ideas around, which may even be correct, but then, as
wolfypack431609 correctly stated, it would be prudent to leave the thread and shut up. The moment you
know something we don't, please tell us, but nobody is interested in your conjecture from facts we all know.
